 When Liszt, after his prolific Weimar years, moved to Rome in 1861, the majority of his works for the next ten years would be religious music for choir.The composition of his most famous oratorio, "Christus", occupied Liszt from 1862 to 1866, with shorter or longer pauses.He finished the score by the end of September 1866, but he wished to make some revisions and corrections, and therefore the work was not completed until the December of that year.
